They're, like, some words you uh... you throw them in when you don't know what to say. Used in the middle of sentences when... um... you're trying to think of a point. Common examples are "uh," "um," and "like." Overuse of them can, like, totally ruin the tone of sentences and make you look weird.
So, uh... this is the part where I, like, put a sentence that uses fillerwords... um... I can't really think of anything.
This from Malay word. It's came from dialek utara semenanjung Malaysia which means have know everything without research first. "pala tau". And to make it nice in writing. Palatao is the best.
